Thanks for your email.
You are free to put it in github and to do and change.

	Hi,

	I'm Simon Monk, I'm currently writing the Electronics Cookbook for O'Reilly. I use your 
	CC1101 library in a 'recipe'. Your library is by far the easiest to use of 
	the libraries for this device, but the .h and .cpp file both reference WProgram.h which 
	as replaced by Arduino.h in Arduino 1.0.

	Rather than have to talk my readers through applying a fix to your library, I'd like 
	your permission to put the modified lib into Github and add an example from the book. 
	I would of course provide a link to your website in the book and mention that you can buy 
	the modules there. If its ok, I'd give the code an MIT OS license, to clarify its use.

	Thanks for a great library,

	Kind Regards,

	Simon Monk.
